SUPPLY-VALVE.

Specification of Letters Patent.

Patented July 20, 1915.

Application filed August 14, 1912. Serial No. 714,972.

To all whom it may concern Be it known that I, EDWARD HARRY NOLAN,

a citizen of the United States of America,

and resident of Cincinnati, county of Ham- .ilton, and State of Ohio, have invented certain new and useful Improvements in Supply-Valves, of which the following is a specification.

My invention relates to supply valves, the

means for closing which are actuated by the water which fills the tank.

The object of my invention is a supply valve, which may be used in an open topped view taken upon line 66of Fig. 1. Fig.

7 is a View, partially in section, of a tank and a water siphon used in connection therewith, and upon line 7-7- of Fig. 1. Fig. 8 is a view partially in section and partially in elevation, of a tank and flush bowl equipped with an embodiment'of my invention.

In the supply valve embodying my invention the inlet valve is closed by a suction,

a which is created at the time the water in the tank has reached its pre-determinedheight,- by the water at the discharge outlet of the valve. 1

Referring to the drawings: I will describe first the means whereby the valve is opened to permit water to flow from the mains into the'tank. Theinlet port a is connected with the chamber 6 of the main or inlet valve B by a channel a, which is below the valve seat I) and is connected with said chamber by a channel 72 in which is'located a choke valve 79 and an adjusting valve 6*. The channel 6 communicates with a chamber D by means of a channel (Z, which is between thechoke valve 6 and the valve 6 Within the chamber D is a-manually actuated valve d, the stem (Z of which is above the manually actuated lever E. When the lever E is raised it lifts the valve d from its seat, the pressure; of water holding the valve B to its seat is then released from the chamber D through the channel 6 channel cl and outlet (Z which is below the seat of valve cl and leads into the tank T. The pressure above the valve B being relieved, water from the mainlifts the valve and passes out into the converging diverging nozzle B. later will thus continue to be discharged, until the valve d is reseated, at which time pressure in the chamber 2) above the valve B will be restored by water passing from the inlet aup through the channel 6 and into the chamber. .The rate at which the water flows from the inlet through the channel 6 is regulated by means of the valve 12 I will nowdescribe the means by which valve (Z is seated, after having been lifted from its seat by the lever E. Thestem d of valve d is engaged by a lever F, which is fulcrumed in the valve casing at f. The lever F is actuated, to reseat the valve d, by means of the piston G, whose stem has a pin 9, which engages an elongated slot 7 in the lever F; The piston G is located in a chamber g, which is open atthe bottom and the upper end of which communicates with the outlet B through a bypass 9 The discharge orifice below the valveseat b is surrounded by a nozzle I) which projectsdownwardly into the nozzle B and cooperates therewith to form an ejector, which, when the valveB is raised, and water is flowing therethrough, is capable of drawing air through the passage 9 from the chamber 9. A groove 9 is formed in the walls of the chamber 9 and is so located that its upper edgeis uncovered bythe piston G when it is moved to its lowest position by the operation of the lever E. This establishes communication between the upper and lower ends of the chamber 9, and consequently permits the ejector-t0 create an unrestricted flow of air through the passage 9 The piston G is provided with a depending flange 9 which cooperates with the groove 9 when the piston is in its lowest position, to form a passage, the lower or inlet end of which is located approximately on a level with the lower end of the chamber 9. With this arrangement the piston G will be moved upwardly as soon as the passage of air through the groove 9 is restricted, sufficiently to create a reduction of pressure 1n the chamber 9 above the piston. The upward movement ofthe piston, G is accomplished as soon as the water in the tank reaches or submerges the lower and open end of the chamber 9.

The first movement of the piston Gr, in response to the reduction of air pressure occasioned by the ejector action, closes the upper end of the groove 9 and shuts off the admission of air to the upper end of the chamber 9. This causes the pressure in the upper end of the chamber to be quickly reduced below the pressure existing in the lower end of the chamber and causes the piston to move up quickly and positively and to firmly seat the valve 0?. The seating of the valve (5 checks the flow of water from the inlet port a, through the passage 19 and the port 6Z3, and causes pressure to pile up in the chamber 6 above thevalve B. This moves the valve B to its seat and shuts off the flow or" water through the nozzle B into the tank. The ejector action ceases as soon as the flow of water ceases, and the air pressure in the upper end of the chamber 9 is immediately increased to atmospheric pressure. The piston G is, however, held in the upper position by the water pressure on the upper face of the valve cl.

The valve 5 is employed to regulate the flow of water through the passages 72 and (Z, so that the valve cZ will not be prematurely closed by water pressure through the passage d. The valve 6 is employed for the purpose of adjusting the delivery of water to the chamber Z), as has been said, and is preferably so constructed that it is capable of a line adjustment, so that the pressure above the valve B will not pile up sufficiently to close the valve B until after the valve d has been moved to its seat. The valve, as illustrated, is located in the tank T at the desired height and is arranged to operate in conjunction with an air bound siphon S, which will empty the tank T as soon as the valve B is closed. It will be understood, however, that the valve may be charge apparatus and that the lever E may be actuated by a manually operable lever, instead of the seat actuated lever L, illustrated.

It will also be understood that various means for creating the reduction of pres sure, or the suction for actuating the piston valve, may be employed; for example, the converging diverging nozzle B may be dispensed with, and the piston G may be actuated by the flow of water passing out of the tank. This may be accomplished by so forming the passage g, that it communicates with the discharge siphon S. With such an arrangement the upper end of the chamber 9 will be subjected to a reduction of pressure, occasioned by the flow of water through the siphon, and the piston will rise in response thereto, and will operate to close the valve d. The passage g will preferably communicate with the inlet side of the siphon and the groove 9 may or may not be employed, as desired. Under some conditions it may be desirable to actuate the piston G in the manner just described, since the valve B, when so controlled, remains open until the flush tank is filled, or until the velocity of discharge through the siphon S is established, at which time it will be positively closed.

In accordance with the United States patent statutes I have described and illustrated the preferred embodiment of my invention, but I desire it to be understood that various changes, modifications and substitutions may be made in the details of construction without departing from the spirit and scope of my invention as set forth in the appended claims.
